Learn MoreIn the modern consumer electronics market, materials must simultaneously fulfill conflicting physical requirements: drop durability (impact resistance) and premium surface feel (scratch resistance). Polycarbonate (PC) boasts extreme impact strength but is highly prone to surface abrasions. Polymethyl Methacrylate (PMMA), conversely, offers optical clarity and a pencil hardness of up to 3H-4H, yet lacks resilience against fractures.
Our advanced Anti-Scratch PC PMMA Sheet Extrusion Line resolves this by employing multi-layer co-extrusion. By bonding outer PMMA layers to an internal tough PC core, the resulting sheet preserves high-impact toughness while elevating raw scratch protection. Incorporating inline UV curing for specialized hard-coating enables outer layers to reach a pencil hardness of 6H to 8H, ideal for smartphone panels, digital kiosks, and wearable touchscreens.

Answering major technical and process questions regarding PMMA/PC composite sheet manufacturing lines.
We utilize an automatic die head controlled by thermal expansion bolts connected directly to an online thickness scanning system. If the sensor detects a thickness variation, the control software alters the lip temperature locally to keep thickness within ±0.01mm limits.
The typical layer arrangement is PMMA/PC/PMMA or PMMA/PC. The PMMA skin thickness usually takes up 10% to 20% of the total structure, providing optimal surface hardness without making the composite sheet brittle.
Yes, our screw geometries and venting options are designed to process up to 30% cleaned industrial regrind or flake materials without creating optical defects or degrading the sheet's mechanical strength.
Our rollers undergo high-grade hardening, grinding, and super-finishing. This results in a surface roughness Ra value below 0.005μm. This finish helps prevent micro-textures on the sheet, meeting optical clarity standards.
